This mini-lesson covers design communication — sketching, isometric & perspective, orthographic working drawings, exploded views, rendering and drawing conventions — and choosing the right method for each audience.

Designers must share ideas with different audiences — clients, users and manufacturers — and each needs a different kind of drawing. Good communication is fit for its purpose and audience: a persuasive render for a client, a precise working drawing for the workshop.
Orthographic projection shows an object as flat 2D views — typically a front elevation, plan and side elevation. Drawn to first- or third-angle convention and fully dimensioned to standards (BS 8888), it is the manufacturing drawing the workshop builds from.
An exploded view separates a product along its axes to show how the parts fit together and in what order — the basis of assembly and maintenance instructions (think flat-pack furniture guides).
Rendering adds tone, shadow, highlight, reflection and texture so a sketch reads as a real object made of a specific material. Media range from marker pens and coloured pencil to digital rendering in CAD.
Tap a drawing type, then tap what it is best used for.
Tap a drawing, then tap whether it is a pictorial (3D) or a working (technical 2D) drawing.
Technical drawings use scale (e.g. 1:1 full size, 1:2 half size, 2:1 double size), a consistent system of dimensioning, standard line types, a title block and projection symbol — all governed by BS 8888 so any engineer can read them.
Always match the method to the audience: a photorealistic render persuades a client; a dimensioned orthographic drawing instructs a manufacturer.
Pictorial: freehand · isometric (30°, parallel) · perspective (vanishing points).
Orthographic: 2D front/plan/side, dimensioned to BS 8888 — the manufacturing drawing.
Exploded: shows how parts assemble; basis of instructions.
Rendering: tone, shadow, texture make a sketch read as a real material.
Scale: 1:1 full · 1:2 half · 2:1 double — drawn length = real × scale.
Audience: render to persuade a client; working drawing to instruct manufacture.
